ALDENBLOSSOM, OF NEWTON SQUARE, PENNSYLVANIA De i e m REGULATING TEMPERATURE- Specification of Letters Patent. Patent d S pt 27 1921 Application filed March 12, 1921. Serial No, 451,703.

To all whom it may concern;

Be it known that I, BLossoM, a Citizen of the United States, residing at Newton Square, in the county of Delaware and State of Pennsylvania, have invented certain new and useful Improvements in Devices for Regulating Temperature, of which the following is a specific i n, er-

ence being had to the accompanyingdrawings.

This invention relates to certain unprovements 1n devices forregu atlng temp ture a and. has relation more. particularly to a de- Vice of this general charact r unde thermo- Static control, and. it is an o jec o th invention to provide a compartment, uch as an incubator, having a plural ty of opengs in communicati n with t e atm sphere, together with means for regulatingor controlling the fiow through said openings.

It is also an object of the invention to provide a compartment, such as an incubator or the like, with a plurality of openings in the upper portion thereof I in, communica-' tion with the atmosphere, one of said openings being larger than the remainder, to-

gether, with automatic means operating to control the flow through said openings.

'Furthermore, it is an object of the invention to provide a compartment, such as an incubator, with an air circulating chamber in the upper portion of the compartment, to-

gether with automatic means for controlling c rculation of air through said chamber inorder to maintain an even temperature -w1th1n the compartment.

The invention consists 1n the detalls of construction and in the combination and arrangement of the several parts of my improved devlce for regulating temperature 'whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth. a

The novel features of my invention will hereinafter be'definitely claimed.

In order that my invention may be the better understood, I will :now proceed to describe the same with reference to the accompanying drawings, wherein; i Fig-urel is .averticalsectional view illustrating a device forregulating temperature constructedin accordance withlan embodime ti f my venti n; r

Fig. 2 is a view similar to Fig.1 illustratlng a further embodiment of my invention; and 1 i f Fig. 3 is a view similar to Fig. 1 disclosng' a still further embodiment of my invention. 7

As disclosed in Fig. 1, Gdenotes a compartment, such as comprised in an incubator or the like, and which is provided in its top walls with the openings 1 and 2., the opening 1 being larger than the opening 2 so that the desired circulation of air within the upper portion of the compartment C is materially facilitated, as the opening 1 serves as an eduction opening and the open- 1ng2 provides an induction opening. I I

Arranged within the upper portion ofthe compartment C is a horizontally disposed frame 3 having disposed thereover a lamination 4 of muslin or other textile material, said laminatione providing an upper air chamber A, Arranged within the chamber A are the heating elements 5, such as steam pipes or the like. By the. provision of lamination the air is caused to circulate from the openings 2 and .l without'coming into contact with the eggs arranged within the trays 6 positioned" within the lower chamber B of the compartment C. 1

' intersect the chamber A and to terminate wlthin the upper portion of the chamber B.

Extending laterally from the lower portion of the member 9 is an arm 10 terminating in a depending extension or arm [11. Pivotally engaged with the lower or freeend portion of the ,arm 11 is a rod or arm 12, the opposite end portion of said rod or arm 12 being pivotally engaged with the lower endortion of a vertically disposed rod 14. 7 he rod 14 extends upwardly through the tubular member 9 and'terminates a desired distance above the block 7. 1

15 denotes an elongated rod slidably disposed through a block orsleeve 16, said rod 15 and block or sleeve 16 being held in supported for swinging movement in a vertical direction.

One end portion of the rod 15 has operatively engaged therewith a depending stem 18 provided at its lower end with a substantially conical-shaped valve member 19. The valve member 19 coacts with the'opening 2 from below and serves to regulate the flow through the opening 2. The opposite end portion of the rod 15 has operatively en gaged therewith adisk 20 which coacts from above with the opening 1 to regulate or control the flow. through said opening. 2

The upper portion of the rod 14 is operatively engaged, as at 21, with the rod 15 so that as the rod 14 moves upwardly or downwardly the rod 15 will be correspondingly rocked. l

22 denotes a thermostat arranged and supported between the arm 10 and the rod 12. When the temperature within the compartment 0, or more particularly the. chamber B, rises above a predetermined degree, as'103 F., the expansion of the thermostat 22 will result in a downward movement of the rod 14 causing the valve member 19 to be lowered and the disk or valve member 20 raised,,resulting in a rapid circulation of air in the chamber A through the openings 2 and 1, the heated air escaping through the opening 1 and the cool air entering through the opening 2. As the temperature within the chamber B lowers, the thermostat 22 will contract, resulting in an upward movement of the rod 14 with the consequent raising of the valve member 19and lowering of the valve member or disk 20, so that the flow of air within the chamber A being retarded whereby an even temperature, preferably 103 F., is maintained within the chamber B.

Adjustably mounted upon the rod 15 and preferablyon the end portion thereof adjacent the diskor valve member 20 is a poise 23 which provides means to assure the requisite balance of the rod 15. I

In the embodiment of my invention as illustrated in Fig. 2, the means for controlling or regulating the flow of air through theupper chamber A is the same as has been hereinbefore described with respect to Fig. 1 except that the valve 19 coacting with the induction opening 2 also cooperates with the delivery end of a pipe or conduit 24 leading within the chamber-A from a point exterior of the compartment C and whereby additional cool air may be delivered within the chamber A. The eduction or delivery end 25 of the pipe 24 is so formed or inclined as to conform to the periphery of the valve member 19 sothat said member 19 in addition to regulating or controlling the flow of air through the opening 2 also coacts for the same purpose with the pipe 24.

In the embodiment of my invention as' illustrated in Fig. 3, the cool air is admitted within the chamber A through the pipe 24 and the flow through said pipe 24 is controlled orregulatediby the flat valve 26 carried by the eduction or delivery end of the pipe 24. Operatively engaged with the fiat valve 26 is the stem 18 carried by the adjacent end of the rod 15'. The rod 15 is supported, and operated in the same manner as hashereinbefore been set forth with respect to the rod 15. The parts illustrated in'Fig. 3 siinilar tofthe parts disclosed in Figs; 1 and 2 are identified by the samereference-characters.- I

From the foregoing description it is p,

thought to be obvious that a device for regulating temperature constructed in accordance' with invention is particularly well adaptedffor use by reason of the convenlowerchamber, an air inlet opening and an air outlet opening in communication with the upper chamber, valves for controlling the iiow through saidopenings, a thermostat within the lower chamber, and means coactautomatically moving the same relative to the coacting openings. v 2, A; device of the class ClGSCIlbGd COIIlprising a compartment provided with an air outlet opening and a plurality of air inlet openings, a valve coacting with the airoutlet opening, a single valve coacting with and common to all of the air inlet openings,
